Rules changes
This season, the Head of Household back to be eligible to compete in the next HoH competition after his leadership, having the chance to be HoH multiple times in a row. Also, he/she gains R$10.000, the Power of No and the right to divide the housemates into two teams for the Food competition. However, for the first time since BBB started, the HoH has no immunity in the nominations, becoming vulnerable to being nominated by the house vote.

You're in control!
